Description

Technical Field

[0001] This utility model relates to the field of digestion instrument technology, specifically to a high-efficiency microwave digestion instrument. Background Technology

[0002] High-efficiency microwave digestion systems are commonly used sample pretreatment devices in laboratories. They utilize the penetrating power and reaction-activating ability of microwaves to accelerate the chemical reactions between organic and inorganic substances in samples. This equipment is typically used for various analytical chemistry processes such as sample digestion, extraction, and protein hydrolysis, and is suitable for sample preparation in fields such as food, environment, medicine, and chemical engineering. Microwave digestion systems can complete sample digestion in a shorter time, improving experimental efficiency while reducing reagent consumption and environmental pollution.

[0003] High-efficiency microwave digestion typically involves sealing the digestion vessel containing the sample and digesting agent to prevent acid leakage during microwave heating. The temperature, time, and microwave power are then set according to the sample's properties and requirements before rapid digestion. However, microwave digestion often generates significant heat due to molecular vibrations, and the cooling rate after digestion is usually slow. A digested sample typically requires a considerable cooling time before analysis, especially when processing large numbers of samples. Slow cooling can extend the entire analysis cycle, impacting work progress. Furthermore, slower cooling means the equipment remains at high temperatures for longer periods, increasing the risk of overheating or damage, and also increasing the risk of burns to operators from contact with the high-temperature equipment.
